OK thank you for your answer... I'm presently using my MacBook Pro as a player either for ripped audio, CD or radio stations on web. The improvement in audio quality is just incredible ! The Apple CoreAudio is simply unbelievable and light-years above most so-called High End players...

Finally, I'm not really motivated to invest time and money in this old CDR 620 recorder/player, even it was a very expensive unit : the launching price was more than 3000 Euros...

All the best,

OndesX

U200 should be cut/removed as this originally supplies u199 with 5v.

Hi Lee

I will remove U199 and replace it with a small pcb with two pins.

Both pins will connect to the sreg output of course.

This small pcb wil have the sreg + output cap..... 220uF BG or 470uF BG.... I did not make my mind yet.

I would use 2x 220uF BG minimum but 2X 470uF BG is fine.

The divider circuit (D1) will gain you much more detail. Not quite as much as you would get with a full C1 but its also much cheaper.

Hi Brent

I was thinking about 1 x 470uF BG on the spower output as I already have 2 x 2200uF Rubycon MCZ on CD15 and CD16...

Is 470 enough ?

More than that will cause placement problems.

I'd have thought you could use even less as you're only powering one little circuit. It will still work and sound great. Quality over quantity!

Hi Ricardo, if you are fitting the reg onto u199, you don't need the BG on the Spower output as cd15 & cd16 are there and close enough to do the job.

Lee.

I assumed Ricardo was fitting the BG to CD15 CD16.

Personally I would remove the MCZ and replace with 2x 470uF (2x 220uF minimum)
